Definitions
- the present invention relates to a board anchor used to mount and fasten various materials to a wall composed of a fragile material.
- Conventional board anchors such as those disclosed in Japanese Utility Model Registration No. 300632, Japanese Utility Model Application Kokai No. 63-16212, and Japanese Patent Application Publication Jitsu Kai Shou No. 3-525) show a male screw provided around the shaft part, having a drill part at one end and a flange part at the other end. At the tip of said flange part is provided a turning tool engagement hole and a female screw formed hole part continuous therewith. Mounting is performed by screwing the mounting screw into the female screw formed hole part. The user only needs to screw the anchor into the board, thereby causing the drill part to form a tap drill hole in the board, whereby a separate tap drill hole step is not required. Next, the anchor is screwed into the board by screwing the male screw of the shaft part into the tap drill hole.
- the drill parts are formed into a flat-pyramid-shaped, flat drill cutting tool, so not only is the resistance great when boring the tap drill hole, but the tap drill hole easily becomes crooked. As a result, the board anchor is screwed crookedly into the board.
- the present invention provides a board anchor that solves the aforementioned problems associated with conventional board anchors.
- the board anchor of the present invention is configured such that a male screw is provided around a shaft part with a drill part at one end and a flange part at the other end; at the end where the flange part is provided, a turning tool engagement hole and a female screw formed hole part continuous therewith are provided.
- Mounting is performed by screwing the mounting screw into the female screw formed hole part; the drill part is formed into a tapered-pyramid shape.
- Multiple split shaft parts are formed by providing a slit that extends from the end surface of the pyramid-shaped drill part to midway up the shaft part.
- the tip of the split shaft part incorporate connected multiple drill bits that are formed by splitting the pyramid-shaped drill part. When a tap drill hole is bored by pushing the tips of the drill bits into a board, the opposing drill bits are displaced in opposite directions, thereby providing a drilling action.
- the tip surfaces of the drill bits are formed into small flat surfaces orthogonal to the axis.
- the multiple split parts deform into a open-legged shape.
- the slit preferably is provided diagonally relative to the pyramid-shaped drill part, but it also may be provided perpendicularly relative to the sides. Multiple slits also may be provided.
- the pyramid-shaped drill part has a quadrangular pyramid shape.
- FIG. 1 a front elevation view of the board anchor of the present invention
- FIG. 2 is a plan view of the board anchor shown in FIG. 1;
- FIG. 3 is the bottom view of the board anchor shown in FIG. 1;
- FIG. 4 is a cross-sectional view along line 4--4 of FIG. 1;
- FIGS. 5(a)-5(d) illustrate how the board anchor of the present invention is utilized.
- FIG. 6 is an enlarged plan view showing the pyramid-shaped tip part when a tap drill hole is formed in the board by means of the pyramid-shaped drill part.
- FIGS. 1 to 4 show the board anchor 1 of the present invention.
- Anchor 1 comprises shaft portion 2, which has drill part 3 at one end and flange part 4 at the other end, and is provided with male screw 5, having a wide pitch and a high screw thread.
- At the flange part 4 end are provided both Phillips hole 6, into which fits a Phillips screwdriver, as well as female screw formed hole 7 that continues to the said Phillips hole 6 and extends toward the drill part 3.
- Drill part 3 is formed into a tapered-quadrangular-pyramid shape.
- the tip surfaces 8 of the pyramid-shaped drill part 3 have small areas and are formed into flat surfaces orthogonal to the axis of the shaft part 2.
- Slit 9 which extends along the axis of the shaft portion 2 from the tip surfaces 8 to the female screw formed hole part 7, is provided diagonally relative to the quadrangular drill part 3.
- Slit 9 forms two split leg parts 10, 10 in shaft portion 2, and the two drill bits 3a, 3b formed by diagonally splitting the pyramid-shaped drill part 3 form the tip parts of both split legs parts 10, 10.
- the cross-sectional shape of both drill bits 3a, 3b is a triangular pyramid shape, and the split tip surfaces 8a, 8b form small, triangular flat surfaces.
- FIGS. 5(a)-5(b) show how the board anchor 1 is used, and in particular, how the fastening of mounted element 22 to gypsum board 21 is accomplished.
- the bit of Phillips screwdriver 20 initially engages the Phillips hole 6 of the anchor 1.
- the tip surfaces 8a and 8b of both drill bits 3a and 3b of the anchor 1 are pushed into the desired position of the board 21, after which the Phillips screwdriver 20 is used to screw in the anchor 1.
- the tip surfaces 8a and 8b of both drill bits 3a and 3b are formed into flat surfaces with small triangular shapes, so they push straight into the board 21.
- the tip parts of both drill bits 3a and 3b are twisted by the resistance force accompanying the rotation of the anchor 1.
- both drill bits 3a and 3b function as drill cutting tools, thereby boring a tap drill hole in the board 21.
- the tap drill hole formed by both drill bits 3a and 3b is bored very smoothly and rapidly by the four corners 11, 11 and 12, 12.
- a nearly perfect circle is formed straight into in the board 21, with no burrs.
- the male screw 5 of the anchor 1 screws into the inner surface of the tap drill hole formed in this manner.
- the conical drill part 3 projects from the back side of the board 21, and the anchor 1 is fastened to the board 21, with the flange part 4 flush with the surface of the board 21 (see FIGS. 5(a) and 5(b)). In this manner, the anchor 1 is mounted by simply screwing it directly into the board 21, without preparing a tap drill hole.
- the mounting screw 15 pushed through the hole 23 of the mounted element 22 is inserted into the female screw formed hole part 7 from Phillips hole 6 of the anchor 1, and the screwing action secures the mounted element 22 to the board 21 by means of the mounting screw 15.
- both split legs 10, 10 of the shaft part 2 are forced apart by the screw 15.
- the male screw 5 cuts into the board 21, so the entire anchor 1 is more firmly fastened to the board 21.
- the openness of both split legs 10, 10 increases with the outside diameter of the mounting screw 15 screwed into the anchor 1, which is convenient.
- slit 9 is provided diagonally along the pyramid-shaped drill part 3, but it also may be provided perpendicularly relative to the sides. Furthermore, multiple slits 9 may be provided. Also, although the preferred shape of the pyramid-shaped drill part 3 is a quadrangular pyramid, it also may be a triangular, pentagonal or hexagonal pyramid.
- the board anchor of the present invention requires no preparation of a tap drill hole in the board, so it is possible to secure a device by screwing the anchor directly into the board.
- a particularly remarkable effect is exhibited in the following instance.
- the drill part provided at one end of the anchor's shaft portion is formed into a tapered-pyramid shape.
- a slit that extends from the tip surface of the pyramid-shaped drill portion to midway up the said shaft part is provided, thereby forming multiple split shaft portions.
- At the tips of the split shaft parts are connected multiple drill bits that are formed by splitting the said pyramid-shaped drill part.
- the tip surfaces of the drill bits bore a tap drill hole by pushing into the board. At this time, the opposing drill bits are displaced in opposite directions, thereby exhibiting superior drilling functionality.
- a tap drill hole is formed easily and rapidly in the board, so it is possible to rapidly and correctly screw the anchor into the board.
